Configuration features
- Separate raw water tank: provides a stable and continuous water supply for the entire system, overcoming the potential instability of water supply in the pipe network. A 304 stainless steel water tank is also available for your convenience. If you need, we can also construct a reservoir.
- Booster pump: provide the required working pressure for each piece of pretreatment equipment.
- Use a stainless steel sanitary water purification pump: The working pressure of the booster pump is calculated based on the designed pressure drop of each pretreatment equipment, with a maximum of 0.05 MPa, and the pressure before the high-pressure pump is a minimum of 0.5 kg/cm².
- Quartz sand filter: The raw water is initially filtered through a mechanical system containing fine-washed quartz sand. This process intercepts flocculants, large particles, and suspended impurities in the raw water. Since mechanical filters captures large amounts of suspended impurities during operation, they must be flushed and backwashed regularly to guarantee the optimal functionality of the filter.
- Activated carbon adsorber: It is necessary to utilize activated carbon filters as the initial treatment stage for reverse osmosis unit. The osmosis system has requirements for the influent index (SDI ≤ 5) and the residual chlorine concentration (below 0.1 mg/L). To meet its influent requirements, the raw water needs to be further purified to meet the influent index for reverse osmosis. A carbon filter is installed before the reverse osmosis device to remove 60% of the water’s organic matter and residual chlorine. Activated carbon can also eliminate odors and pigments from water and enhance water clarity.
- Antiscalant dosing device: The reverse osmosis membrane is the key component of the entire system. The continuous operation of the equipment will inevitably cause calcium and magnesium ions to precipitate and adhere to reverse osmosis membrane surface, forming scale and blocking the membrane pores. This will impair the efficiency of the reverse osmosis system and damage the reverse osmosis membrane. It is recommended to introduce a dosing system to add reverse osmosis scale inhibitors to the water to delay the precipitation of calcium and magnesium ions and scaling on the membrane surface. An automated metering dosing pump can be utilized for precise metering and dosing.
- Fine filter: Fine filter is also called security filter. This process occurs before the raw water enters the reverse osmosis membrane unit. The PP filter element is designed to achieve large filtration flows, significant pollution-holding capacities, and minimal pressure loss. This innovative technology is able to intercept impurity particles of different sizes, combining surface filtration and depth filtration in a single, efficient process.
- High-pressure pump: The high-pressure pump is essential to the reverse osmosis system, ensuring the requisite working pressure for water flow and quality.
- Single-stage pure water host device: Raw water passes through a membrane under high pressure. This pressure allows the solvent in the water to diffuse from a high concentration to a low concentration, thereby achieving water separation, purification, and concentration.
