West water treatment equipment, pure water equipment, reverse osmosis equipment, set production system water treatment desalination
Source water: urban tap water, groundwater (need to detect water samples), > 0.3 MPa water pressure, water conductivity < 800 mu s/cm;
When the feed water conductivity > 800 mu s/cm, it is recommended to use two-stage reverse osmosis.Effluent standard: national purified water standard} {GB17324-2000 2, pure water equipment technological process
Three water, pure water equipment design
1, adjust the water tank (pool) : generally USES P E, stainless steel water tank, also can use reinforced concrete pool, the main reservoir, buffer, the action of precipitation in the water and sediment.More than 2, the first level pretreatment system: adopting the medium filter, according to the raw water quality using quartz sand and manganese sand filter materials, KDF filter media, the main purpose is to remove the water contain of sediment, rust, colloid substances, suspended solids and single particle size in 20 microns above harmful substance, make water is less than 0.5 NTU turbidity, COD is less than 1.5 mg/L, iron content is less than 0.05 mg/L;SDI 5 or less;Can use semi-automatic, automatic control valve, control the filtering and backwash.
3 and 2 pretreatment system: adopting activated carbon filter, the purpose is to remove the pigment in the water, smell, biochemical organic matter, reduce the value of the residual chlorine in water and pesticide pollution and other pollutants.
4, the third class pretreatment system: adopting Yang resin softening, main is to reduce the water hardness, remove the calcium and magnesium ions in the water (the main components of the scale forming), which can effectively extend the service life of reverse osmosis membrane, and the intelligent resin regeneration.
5, dosing system: according to the raw water quality, choose different types of scale inhibitors, can control the content of phosphate, sulfate, calcium, effectively prevent reverse osmosis membrane fouling.6, 4 pretreatment system: adopting 5 microns diameter precision filter, makes a further purification, water to water turbidity and chromaticity of the standard.
7, pure water equipment host: reverse osmosis technology is adopted to improve the depth desalting, removal of calcium, magnesium, lead, mercury and other harmful heavy metals and other impurities, reduce the hardness of water, desalination rate above 99%, and produce the pure water conforms to the national standard.
8, two-stage reverse osmosis host: by level 1 reverse osmosis treated water, again through the second reverse osmosis processing, make the purified water quality further, is suitable for the user or the source water quality is poorer, the special requirements of the special industry.
9, cleaning device: regular use of drugs to reverse osmosis membrane cleaning, ensure that the service life of membrane and water quality standards.
10, sterilizing system: using ozone generator sterilization, reduce bacterial secondary pollution, sterilization rate can reach more than 99%, the ozone in the air back into O2, without any harmful residues.Ozone oxygen-rich water soluble in water at the same time, guarantee pure fresh water.
11, water storage system: adopt stainless steel water tank, equipped with automatic level control system, water full automatic stop, automatic management.
12, filling system: automatic filling machine (drum, small bottle) sterile pure water, mineral water) in the state of security seal products into container.Four, pure water production equipment, etc
1, after startup, pure water equipment to realize automatic membrane washing function flush time 2 to 10 minutes, adjustable.2, equipment, waste water reflux device, can be secondary to water use, improve the utilization rate of water and save water.
3, low voltage protection system, when the source water pressure is insufficient or passive water equipment, automatic stop, protect the security of the high pressure pump and equipment.4, with cleaning and maintenance system, can regularly to cleaning and maintenance of equipment, prolong the service life of reverse osmosis membrane for 3 to 5 years.5, stainless steel frame structure, the realization of health dead Angle, equipment corrosion, using 10 to 20 years is still like new.
6, two-stage reverse osmosis devices have multiple regulator, which can realize double water, single stage or single stage and at the same time, water to produce diversified water quality.7 with mineral water equipment, reverse osmosis equipment (equipment) mountain spring, v to reduce investment cost, improve the utilization of water resources.8, with online water quality meter and flow meter, observe the effluent water quality and water rate, operation parameters, such as water utilization.9, after the expiration of the pure water tank water device can automatically stop, equipment basic can achieve unattended operation 24 hours a day. |
