The water softener softens hard water through ion exchange.
Calcium and magnesium ions in natural water are the main causes of hard water, and they are prone to scale formation. The Water Softener is equipped with resin beads, which are negatively charged and adsorb sodium ions. When hard water flows through the resin, calcium and magnesium ions with stronger positive charges will replace the sodium ions on the resin and combine with the resin. The replaced sodium ions flow out with the water, resulting in "soft" water.
What are the main problems that arise during the operation of circulating water?
The main problems that arise during the operation of circulating water are:
(1) Scale: As the circulating water evaporates continuously during the cooling process, the salt concentration in the water continues to increase, exceeding the solubility of certain salts and precipitating. Common scales include calcium carbonate, calcium phosphate, magnesium silicate, etc.
Definition of knowledge about metering pumps
A metering pump is a special volumetric pump that can meet the needs of various strict process flows, and the flow rate can be adjusted steplessly within the range of 0-100%, and is used to transport liquids (especially corrosive liquids). A metering pump is also called a metering pump or a proportional pump.
Reasons and solutions for the mud not being dry when the snail stacker is discharged
Reasons: 1. Flocculation problem. Due to the snail stacker's particular operating principle, the sewage treated by the snail stacker must be treated with drugs in the early stages. After the sewage is flocculated and precipitated, it is pumped into the equipment for dehydration. The compatibility of the agent and the sewage, the proportion of the agent added, the solubility of the agent, etc. will affect the size of the flocs in the sewage.
Under what circumstances does reverse osmosis need to be flushed?
Initial startup: Low-pressure flushing with pre-treated raw water is required, mainly to remove the air in the pressure vessel. The membrane element should be flushed for at least 6 hours when it is a dry membrane, and at least 30 minutes when it is a wet membrane.
Things to note when adding alkali to reverse osmosis to increase desalination rate
In primary Reverse Osmosis, alkali is used less to add alkali, and alkali is injected into reverse osmosis inlet water to increase pH. The only alkali agent used is sodium hydroxide (NaOH), which is easy to purchase and is easy to soluble in water.
What adverse effects will the increase in water temperature have on ultrapure water equipment?
The normal operation of ultraPure Water equipment has certain requirements for the inlet water temperature. Too high or too low will affect its performance. So, when the water temperature rises, what specific adverse effects will it have on the ultrapure water equipment?
Why do we need to add antiscalant to reverse osmosis equipment?
Reverse osmosis (RO) technology is a "purification weapon" in the field of water treatment, but do you know? If the core component of RO membrane wants to operate stably for a long time, it cannot do without an "invisible guardian" - antiscalant. Why must it be added? How does it protect the membrane? Today, we will unveil the mystery of antiscalant!
Pleated filter product features
As an important industrial filtration equipment, the pleated filter element has been widely used in many fields due to its excellent chemical compatibility, corrosion resistance, large filtration area, strong dirt holding capacity, and long service life.
Inventory of pollution suffered by ion exchange resin operation
Ion exchange resin is widely used in water treatment systems, but its performance is easily affected by a variety of pollutants, resulting in reduced exchange capacity and deterioration of effluent water quality.
