Unlike traditional manual filters, the automatic backwash filter uses a built-in automatic control system to continuously remove dirt on the filter screen, ensuring that the equipment maintains a good filtering effect during long-term operation.

If the rust particles in the well water are large, a filter of 10 to 20 microns can be selected; if the rust particles are fine, a filter of 5 to 10 microns should be selected.

The cheapest water treatment method is 1. Boiling 2. Solar Disinfection (SODIS) The most effective water treatment method is 1. Reverse Osmosis (RO) 2. Ultraviolet (UV) Disinfection 3. Ozone Disinfection

A rotating drum filter is a device that uses a rotating filter drum for solid-liquid separation. It mainly consists of a rotating drum with filter media, drive device, backwash system and housing.

Tertiary system wastewater treatment, also known as deep treatment or advanced treatment, is a process of further purifying wastewater after primary and secondary treatment. Its main purpose is to remove dissolved organic matter, inorganic matter, pathogens etc.

The reverse osmosis system can remove most contaminants in the water, including dissolved minerals, organic matter, bacteria and viruses. It is not only suitable for borehole water treatment, but also widely used in seawater desalination, wastewater treatment and other fields.

Water treatment equipment in the glass industry includes: 1. Filtration equipment 1.1 Sand filter 1.2 Activated carbon filter 2. Ion exchange equipment 3. Ultrafiltration equipment 4. Reverse osmosis equipment 5. Neutralization equipment 6. Biological treatment equipment

Deodorants that can remove odors from wastewater: 1. Activated carbon, 2. Oxidants, 3. Biological deodorants, 4. Chemical precipitants, 5. Adsorbents. Scientists and engineers have developed a variety of deodorants for different odor components in wastewater.

Common filter media in drinking water treatment are: 1. Activated carbon, 2. Quartz sand, 3. Ceramic filter element, 4. Anthracite, 5. Ion exchange resin.

● Water output (Qp): 30,000 liters per hour ● Recovery rate (R): 60% ● Calculate the recovery rate using the formula: Qin = Qp/R ● Substitute the known values ​​into: Qin = 30,000 liters per hour/60% = 50,000 liters per hour
