Your Trusted RO Water Maker Manufacturer

RO Water Maker of NEWater

NEWater RO water makers employ a multi-step process for water purification and making. It begins by reducing the conductivity and hardness of the water. This is done by using cationic-specific and anionic-specific resins that remove positive and negative ions, respectively, from the water that is being treated, so that it may meet industrial standards worldwide. Once these unnecessary ions are removed, the water is pressurized using hydro pumps and is made to cross a series of membranes that use the concept of osmosis to filter the water. The membranes have different pore diameters and thus retain solid waste of different molecular weights.

NEWater’s RO water maker also employs post-treatment methods. For example, use easy-to-program activated carbon filters and UV sterilizers! Just email NEWater, and get all your water treatment questions!

The Ultimate FAQ for Reverse Osmosis Watermaker

Fresh product water in boats, cruise ships, and yachts is paramount for the crew, passengers on board, and general boat maintenance. Contemporary water vessels have replaced freshwater tanks with efficient desalinators that generate potable water from seawater.

With the infinite availability of seawater, sea travel is made virtually limitless, as boat operators are able to remedy water scarcity issues. By providing top-notch RO watermakers, NEWater facilitates convenient and cost-efficient voyage and cargo shipment.

➣What is Reverse Osmosis?

With respect to seawater desalination, reverse osmosis is an elaborate process that eliminates or fundamentally shrinks the concentration of dissolved solids from seawater. Reverse osmosis is deployed to generate fresh product water by lowering the TDS proportions of seawater.

Reverse osmosis is a technology widely applied in distinct industries thanks to its impeccable productivity, reliability, and cost-efficiency. Recently, it has been the subject of great interest from boat operators given it allows practical conversation of seawater into product water.

➣What is a Reverse Osmosis Watermaker?

Portable reverse osmosis desalinators utilized in water vessels to supply fresh potable water are referred to as RO watermakers. Essentially, they are compact water treatment devices utilizing reverse osmosis processes to provide high-quality product water for boat applications.

Typically, reverse osmosis watermakers lessen the salinity concentration in seawater thereby making seawater fit for human consumption and safe for vessel maintenance. Ordinary seawater averages a TDS score of 35,000ppm and RO watermakers shrink the TDS rate to below 1000ppm.

NEWater manufactures a diverse range of RO water makers accommodative of small boats, yachts, medium vessels as well as enormous cargo ships. Our RO water makers have a small footprint allowing users to economize on space.

➣How do Reverse Osmosis Watermakers Function?

Reverse osmosis watermakers function similarly to ordinary seawater desalination systems. Due to the high salinity concentration in seawater, which is the primary source of feed water for watermakers, reverse osmosis is the only viable water treatment technology.

Reverse osmosis is technically a multi-stage process that can be repeated severally to attain high-quality permeate i.e. two-pass reverse osmosis. Underneath, we look at the elaborate RO process utilized by watermakers to treat seawater.

Pretreatment.

To begin with, the feed water is driven into a pretreatment unit composed of pre-filters and a chemical dosing system (optional). In a physical separation process, the sediment filters alienate seaweed, colloids, and other debris from the seawater while carbon filters eliminate awful smells and tastes. For highly alkaline seawater, a chemical dosing unit is enforced to nullify the corrosion and scaling threat of the feed water.

Primary treatment.

The pretreated feed water flows through the perforated RO membranes under high pressure. The regular osmotic flow is reversed by the pressure pumps thereby instigating the flow of water from high concentration to low concentration.

Courtesy of the membrane’s miniature pores (0.0001 microns), dissolved salts, viruses, bacteria, arsenic, calcium, and metals are filtered out. The filtered water devoid of dissolved solids is harvested separately as well as the generated brine.

Post-treatment.

This is the final reverse osmosis step, which is broadly informed by the destined use of the product water produced. For example, drinking water necessitates remineralization since the RO membranes eradicate virtually all minerals. Typically, the permeate is injected with 10 mg/L of magnesium and 30 mg/L of calcium.

➣What are the Various Applications of RO Watermakers?
