Whole-house water filtration systems can be roughly divided into the following categories: 1. Sediment Filters: 2. Activated Carbon Filters: 3. Ion Exchange Systems: 4. Reverse Osmosis Systems: 5. UV Purification Systems: 6. Whole-House Comprehensive Filtration Systems:

The quality of groundwater is affected by the geographical environment, soil structure, rock composition and human activities. For example, groundwater in some areas may contain high concentrations of iron, manganese, sulfide or high hardness, resulting in yellow water, odor, scaling and other problems.

A 250L/H RO machine performs well in meeting water quality requirements. Based on an 8-hour business day, this device can provide up to 2,000 liters of pure water per day. For a small or medium-sized coffee shop, the daily water consumption for coffee making is usually between 500 and 1,500 liters.

● 8040 reverse osmosis membrane: Due to its larger diameter, the surface area of ​​the membrane is usually between 365-400 square feet. ● 4040 reverse osmosis membrane: Due to its smaller diameter, the surface area of ​​the membrane is between 85-100 square feet.

If the filtered water quality is significantly reduced, the TDS value (total dissolved solids) is increased, or the water outlet speed is significantly slowed down, the reverse osmosis membrane should be considered for replacement.

Main types of water treatment machines: Reverse osmosis (RO) water treatment machine Ultraviolet (UV) disinfection water treatment machine Activated carbon water treatment machine Water softener Ultrafiltration (UF) water treatment machine Electrolysis water treatment machine

Activated carbon filtration is one of the most widely used non-reverse osmosis water treatment technologies, especially in household water dispensers and filter jugs. It has a strong adsorption capacity and can remove organic matter, residual chlorine, odor and some heavy metals in water.

Under-counter water purifier is a water purification device installed under the kitchen sink. Unlike traditional countertop water purifiers, it mainly saves space through hidden installation, and directly supplies filtered clean water through a special faucet or connected to the existing water pipe system of the home.

Components of portable desalination devices: 1. Water Intake System 2. Pre-treatment System 3. High-pressure Pump 4. Reverse Osmosis Membrane 5. Brine Disposal System 6. Freshwater Storage System 7. Power Supply System 8. Control System

Well water and groundwater usually contain more silt, rust and organic matter, and the hardness is also high. In this case, it is recommended to install a mechanical filter or activated carbon filter first, and then install a water softener to ensure a comprehensive improvement in water quality.
