Need for RO Systems in Sanitizer Manufacturing Companies

Sammy FaragAMPAC USA — May 15, 2020

Need for RO Systems in Sanitizer Manufacturing Companies

By .
Quick Answer: Seawater reverse osmosis (SWRO) desalination forces seawater at 800–1200 PSI through polyamide membranes, removing 99.7%+ of dissolved salts to produce potable water. Modern systems achieve energy consumption of 2.5–4 kWh per cubic meter with pressure energy recovery devices, making SWRO the most energy-efficient large-scale desalination technology available.

The demand for sanitizers has shot up due to COVID-19. To meet it with quality, sanitizer manufacturing companies must consider commercial reverse osmosis systems that will help ensure that the products are as pure as they can be. As the future of sanitizer manufacturers is bright, they must invest in the production process wisely to make the most of this opportunity.

Since the outbreak of coronavirus pandemic, people have become more health-conscious than ever. Even the US Centers for Disease Control and Prevention has advised people to use alcohol-based (at least 60%) sanitizers to kill the deadly virus. As a result, the demand for sanitizers has multiplied many times. The demand won’t die out anytime soon as there is no vaccine for COVID-19 and the world will have to live with it for at least a couple of months.

Here are the few reasons why hand sanitizers’ demand has shot up

  • It provides waterless protection from germs.
  • Hand sanitizers help you maintain a basic hand hygiene routine.
  • It is a high-performance product with good results.
  • It is a cost-effective option.
  • Hand sanitizers are also among green and sustainable solutions.
  • It is a user-friendly product as people of all ages can use it easily.
  • Studies have proven that hand sanitizers actually work.
  • It is created by using sophisticated technologies.
  • It is a preventive healthcare tool.

Key Types of Hand Sanitizers

The key types of hand sanitizers are:

  • Sanitizers Based on Alcohol
  • Sanitizers Based on Essential Oils
  • Sanitizers Based on Triclosan
  • Alcohol Wipes

Need for Water in Sanitizer Manufacturing Companies

The WHO has suggested two formulations of hand sanitizers. One includes ethanol 96% v/v, 833.3 ml, glycerol 98%,14.5 ml, H2O2 3%, 41.7 ml and pure water. The second includes isopropyl alcohol (with a purity of 99.8%), 751.5 ml, H2O2 3%, 41.7 ml, glycerol 98%, 14.5 ml and pure water.

What flow rates are available for emergency water treatment?

AMPAC USA's emergency systems range from 1,500 GPD portable units to 50,000+ GPD trailer-mounted systems. Military-specification units are available for forward operating base deployment, producing potable water meeting EPA and WHO drinking water standards from virtually any source.

Are emergency RO systems suitable for disaster relief operations?

Yes. AMPAC USA's emergency systems are used by FEMA, the U.S. military, and international NGOs for disaster relief. They treat flood water, contaminated groundwater, and brackish sources, removing bacteria, viruses, and chemical contaminants to produce safe drinking water on-site.

What power sources can emergency water purification systems use?

AMPAC USA's emergency systems can run on generator power (120/240V or 480V 3-phase), solar panels with battery backup, or vehicle power take-off (PTO). Low-power models consume as little as 0.5 kW, making them viable for off-grid deployment.

How durable are military-grade water purification systems?

AMPAC USA's military systems are built to MIL-SPEC standards with stainless steel frames, powder-coated components, and UV-resistant materials. They are designed to operate in temperatures from -20°F to 120°F and are vibration-tested for transport in military vehicles.

Conclusion

This post highlighted how emergency and military-grade water purification systems provide safe drinking water rapidly in the most challenging field conditions. For organizations requiring deployable water treatment capability, AMPAC USA engineers portable and trailer-mounted systems built to perform wherever they are needed.

Seawater Reverse Osmosis: Process Engineering and Design

Seawater reverse osmosis (SWRO) has become the dominant global desalination technology, accounting for the majority of new capacity additions worldwide. The process exploits the semi-permeable properties of thin-film composite polyamide membranes to separate water molecules from dissolved salts. Standard seawater contains 30,000–45,000 mg/L TDS (total dissolved solids), primarily as sodium chloride with significant concentrations of magnesium, sulfate, calcium, and bicarbonate. Overcoming the osmotic pressure of seawater (27–30 bar) requires high-pressure pump systems operating at 55–85 bar (800–1200 PSI).

Energy consumption was historically the major limiting factor for SWRO adoption. Modern systems achieve significant energy reduction through pressure energy recovery devices (ERDs) — isobaric energy exchangers that transfer hydraulic pressure from the high-pressure concentrate stream to the incoming feed water. State-of-the-art ERDs (Pressure Exchanger™, Turbocharger) recover 90–98% of the energy in the concentrate stream, reducing net energy consumption from 8–10 kWh/m³ (older technology) to 2.5–4 kWh/m³ for modern large-scale plants. Coupling SWRO with renewable energy (solar PV, wind) is increasingly feasible at this energy intensity.

Pre-treatment is the most variable and critical aspect of SWRO system design. Coastal and offshore feed water contains algae, bacteria, suspended solids, and organic matter that can irreversibly foul SWRO membranes in hours without proper conditioning. Pre-treatment trains typically include coarse screening, dissolved air flotation (DAF) or sedimentation, dual-media or anthracite/sand filtration, cartridge filtration (5 micron), and chemical dosing (antiscalant, biocide, acid for pH control). AMPAC USA SWRO systems include comprehensive pre-treatment and automated control systems designed for remote marine, island, and coastal installation environments.

Q: What is the typical recovery rate for seawater RO systems?

A: SWRO systems typically operate at 35–50% recovery — meaning 35–50% of the seawater fed into the system becomes product water. This is significantly lower than brackish water RO (60–85%) due to the high osmotic pressure and fouling potential of seawater.

Q: How much energy does seawater desalination consume?

A: Modern SWRO systems with pressure energy recovery consume 2.5–4 kWh per cubic meter of product water. Older systems without energy recovery consumed 8–10 kWh/m³. Solar-powered SWRO systems are increasingly viable for remote locations.

Q: What are the main pre-treatment requirements for SWRO?

A: Seawater pre-treatment typically includes coarse screening, sedimentation or DAF, multi-media filtration, 5-micron cartridge filtration, antiscalant dosing, and biocide treatment. Ultrafiltration membranes are increasingly used as enhanced pre-treatment for high-turbidity feeds.

Q: How long do SWRO membranes last?

A: With proper pre-treatment and operation, SWRO membranes typically achieve 5–7 year service life in well-designed systems. Poor feed water quality, inadequate pre-treatment, or operational issues (pressure spikes, biofouling) can reduce this significantly.

Q: What happens to the concentrated brine reject from SWRO?

A: SWRO concentrate (brine) at 60,000–90,000 mg/L TDS must be carefully managed. Coastal plants typically discharge to the ocean through diffuser systems to minimize local salinity impact. Inland SWRO plants face greater challenges, often using evaporation ponds, deep-well injection, or zero-liquid discharge (ZLD) systems.

Q: Can SWRO systems operate reliably in remote locations?

A: Yes — containerized SWRO units with automated control systems and remote monitoring are designed for marine vessels, island communities, and offshore installations. AMPAC USA builds compact SWRO systems rated for continuous unmanned operation with automated chemical dosing and alarm systems.

Frequently Asked Questions

Q: How does reverse osmosis remove salt from seawater?

A: High-pressure pumps force seawater through semi-permeable polyamide membranes with pores approximately 0.0001 microns — too small for hydrated salt ions to pass through. Water molecules pass; sodium, chloride, and other dissolved salts are rejected at 99.7%+ efficiency.

Q: What is the typical recovery rate for seawater RO systems?

A: SWRO systems typically operate at 35–50% recovery — meaning 35–50% of the seawater fed into the system becomes product water. This is significantly lower than brackish water RO (60–85%) due to the high osmotic pressure and fouling potential of seawater.
