A Reverse Osmosis Company
The process utilized by reverse osmosis company, Coster Engineering, is a water separation technology where dissolved contaminants in water are physically removed by passing under pressure through a semipermeable, thin film membrane. The process is similar to the way your body’s cells absorb water.

Reverse osmosis will remove up to 98% of dissolved contaminants such as: minerals, salts, metals and organic matter that may be present in a water supply. Pores in the reverse osmosis membrane are so small that only water molecules pass through. The contaminants are rejected and discarded as wastewater. A comparison of the molecular size to pore size of the reverse osmosis membrane is shown to the right.
Many customers desire Reverse Osmosis water for drinking and cooking to reduce health risks associated with contaminated water. Coster Engineering offers a wide variety of products to fit all of your water-needs. We often refer to our water vending machines as your 24-7 cash machines because they do the work for you and provide pure water for your customers.
