1、 Equipment name: domestic rainwater filtration and treatment equipment

2、 Specification and model: hdnys-15000l

3、 Equipment brand: Wenzhou Haineng wzhdn

4、 Product function description:

According to the actual situation of rainwater collection, water quality requirements, For the purpose of economy, convenience and practicality, the following filtration system processes are adopted to prepare domestic water to meet the needs of daily domestic water consumption of the unit personnel, and the safety problems of drinking water for the unit personnel are thoroughly solved with low cost and high efficiency, so as to ensure the health of the staff. The process flow and equipment configuration (15t / h rainwater system) involved in this scheme is as follows: Designed to meet the actual needs of your daily life water.

1. Multi media filter:

It is mainly used to remove rust, sediment, algae, suspended solids and other impurities in the water, reduce the turbidity of the water, make the turbidity of the water less than 0.5ntu, CODMn less than 1.5mg/l, iron content less than 0.05mg/l, SDI ≤ 5. The control valve can be used for back washing and forward washing at any time to wash off the dirt on its surface, prevent it from blocking and restore its filtering capacity.

2. Activated carbon filter:

Activated carbon has a very strong adsorption and filtration performance, and has a strong adsorption effect on residual chlorine, heterochromatic, peculiar smell, organic matters, etc. in water. As the reverse osmosis membrane is very sensitive to residual chlorine and organics, it is necessary to configure activated carbon to absorb residual chlorine and organics, so that the residual chlorine in the outlet water is ≤ 0.1mg/l, SDI ≤ 4, the first can meet the water supply requirements of the reverse osmosis membrane. Second, it can greatly improve the original taste of the source water. It can be backwashed at any time through multi-channel control valve or steam operated butterfly valve to wash away the colloid and other pollutants on its surface, prevent the surface of the activated carbon from being surrounded by impurities, prevent it from blocking, and restore its treatment capacity.

3. Precision security filter:

After pre-treatment, PP filter element (with framework and good strength) with loose outside and tight inside is used, and water is filtered from outside to inside, which can prolong the time when the filter element is blocked. The upper part has an exhaust valve and the lower part has a drain valve, which can discharge the retained impurities at any time. The filtration accuracy is less than 1um, far exceeding the standard of tap water.

4. Automatic backwash control device:

Adopt multi-functional multi-channel valve control head, implement full-automatic back flushing, positive flushing, and operation, no need for manual integrity, safe and reliable.

5. UV sterilization bacteria:

It adopts the UV sterilization of Philips to make the water more safe and sanitary.

5. Features:
◇ automatic and manual operation / flushing

◇ high water level automatic shutdown and low water level automatic startup

◇ voltage loss, undervoltage, overcurrent, short circuit, open circuit, leakage protection

◇ the equipment is made of stainless steel, fully automatic operation, and no need for manual conduct.

◇ enterprises of all walks of life occupy a large area, use rainwater collection, filtration, treatment and reuse, cost saving and energy saving and emission reduction meet the requirements of environmental protection!

1. The influent water quality is rainwater or equivalent water source.

2. Technical indicators of water production:

(1) Water production flow: 15 tons / h (water temperature 25 ℃) domestic water requirements

(2) Water production standard: in accordance with national standard a for reverse osmosis equipment design (GB / T 19249-2003)

(3) In line with the national standard for water quality for domestic use cj94-2005

(4) Generally, there is no total hardness in rainwater, and the hardness is less than 0.03mmol/cm)

1. The system equipment is entitled to one-year free warranty, the warranty date is calculated from the date of product acceptance, and the consumable filter material is not listed here.
2. In case of any equipment quality problem (except caused by misoperation or unforeseen factors) during the warranty period, the supplier shall repair it free of charge and replace the damaged parts.
3. After the expiration of the warranty period, only a certain material fee and appropriate technical service fee will be charged.
4. In case of system operation failure which cannot be solved by itself or by telephone, our technical maintenance personnel shall make solutions (including temporary measures) and schedule within 24 hours after receiving the written notice from the demander and report to the competent leaders of both parties.
5. After the delivery of the equipment, our company will have engineers to pay a return visit to understand the operation of the equipment and provide technical services in a timely manner. Users are welcome to ask any technical questions, and we will reply in time.

① the user shall provide detailed data of raw water test, so that our company can carry out relevant selection and arrangement calculation.
② the user shall explain the water quality requirements, use and water yield of the produced water.
③ our company has many types of pressure vessels, membranes, accessories, etc. if the user gives special instructions, we will try our best to meet the requirements.
④ our company provides installation and debugging for the designed and sold equipment and training for the user's operation personnel.
⑤ our company implements the principle of one-year equipment warranty and lifelong service for users, and establishes archives for tracking service to ensure the quality level.

If the above equipment fails to meet your requirements, please contact us, and we will make a detailed engineering plan according to your actual situation, to achieve a low-cost, high efficiency and scientific process combination, so that the water production can meet your ideal requirements.
