Sewage Treatment Plant table top reverse osmosis water purifier

We specialize in manufacturing small and medium size RO systems 3 with flowrates from 0.5 to 1,000 m /hr for various industries and applications, from drinking water purification and sea water desalination to production of ultrapure water used in electronics and chemical industry.

Main features include fully automatic PLC control, highly permeable membranes, optional energy recovery system, precise measuring and control instruments, low energy consumption, automatic rinse function, low/high voltage protection, emergency alarm and shutdown, compact size, and many others.

RO Filtration

RO filtration is achieved by using high pressure to overcome the osmotic pressure and drive pure water out of the concentrated solution through semipermeable membrane. RO filtration removes suspended solids, large ions, bacteria, viruses, colloids, organic matter, and up to 98% of soluble salts. It can be used for several purposes from basic water purification to separating and concentrating various solutions for manufacturing or research applications. RO filtration is an advanced treatment method with low operating cost, high efficiency, and small footprint.

RO System Configuration

Typical RO system includes three main components: pretreatment, RO filtration, and posttreatment. Pretreatment is used to improve raw water quality, protect RO membranes from fouling, and prolong system life time;

RO module is a key element of the system. RO membranes can remove up to 98% of soluble salts and large ions, almost 100% of pathogens, colloids, and small suspended solids. RO module consists of high pressure pump, RO unit, and RO rinsing system;

Post treatment can be used to further remove salts and ions (EDI, Ion Exchange resins) or to disinfect water (UV disinfection). Main purpose of post treatment is to improve water quality and meet customer’s requirements.

Components

Raw water tank---Intake pumps---Multi-media filter---GAC filter---Sand filter---Softener---Cartridge filter---1st high pressure pump 1st pass RO module---Interstage storage tank 2nd high pressure pump 2nd pass RO module Disinfection Product water tank Product water pump-Distribution system.

Functions of the components

Raw water tank: used to store raw water; also provides additional time and space for sedimentation;
Sand filter: removes large particles, suspended solids and silt content;
GAC filter: adsorbs residual chlorine, TOC, controls color and odor;
Softener:  filled with cation resin to remove calcium and magnesium,reduce water hardness, and prevent scaling on the RO membranes;
Cartridge filter:  a pore size of 5 microns; removes larger mechanical particles and prevents damage to the membrane;
RO module: main element; removes large ions, soluble salts, colloids, and small suspended solids;
Product water tank:  stores purifier
