Station for complex water treatment SKO-10K. One of the first steps in most conventional water purification processes is the addition of chemicals to assist in the removal of particles suspended in water. Particles can be inorganic such as clay and silt or organic such as algae, bacteria, viruses, protozoa and natural organic matter.
The conventional treatment method for water purification is a complex, multistage process that was used for many years. [10] It generally consists of five primary steps. [11] First, raw water is adjusted for alkalinity and pH with the addition of hydrated lime and carbon dioxide.
Water purification combines a number of methods to produce potable or drinking water. Downstream processing refers to purification of chemicals, pharmaceuticals and food ingredients produced by fermentation or synthesized by plant and animal tissues, for example antibiotics, citric acid, vitamin E, and insulin.
A RO unit delivering 20 liters (5.3 U.S. gal) of treated water per day also discharge between 50 and 80 liters (13 and 21 U.S. gal). This led India's National Green Tribunal to propose a ban on RO water purification systems in areas where the total dissolved solids (TDS) measure in water is less than 500 mg/liter.

Depending on the type of application and on the media used for microbial growth, bioclogging can be controlled using physical and/or chemical methods. Backwash steps can be implemented using air and/or water to disrupt the biomat and recover flow whenever possible. Chemicals such as oxidizing (peroxide, ozone) or biocide agents can also be used.
