Comprehensive hospital sewage treatment equipmentThe selection method:
1. Choose the material, which is the material of the integrated sewage treatment equipment tank body. There are currently materials available in the market such as stainless steel, fiberglass, cast iron, aluminum, food grade resin, or PVC. The first three materials have relatively good compressive strength and can be used as pre filters (central units). The latter two materials have relatively poor compressive strength and can only be used at the rear end of the pre filter (central unit) for direct drinking machines. Among these materials, stainless steel has better compressive and corrosion resistance. The price is also relatively high. Food grade resins or PVC have poor compressive strength and relatively low prices.

From a functional perspective, first of all, I understand the purpose of choosing an integrated sewage treatment equipment. Purifying water is to remove sediment, impurities, bacteria, heavy metals, residual chlorine, organic matter, and some minerals from the water. The key to selecting suitable functions is how to reasonably match the composition of filter media.

3. Regarding the qualification of integrated sewage treatment equipment, the Health Monitoring Center of the Ministry of Health of the People's Republic of China has issued a clear statement on the management methods for monitoring and controlling the hygiene of drinking water. Article 21 of the statement clearly states that all products without the health approval issued by the Ministry of Health are considered 'unlicensed driving' and are not protected by law.
