drinking water treatment: carbonate removal and/or softening

drinking Water treatment: carbonate removal and/or softening

When the water has a high TH accompanied by a significant M-alk., the water can be softened by using lime to remove the carbonate. This carbonate removal can be carried out: "catalytically" by Gyrazur when no concomitant clarification is needed and when the magnesium content is low;

water softening

Water softening

Recharge typically takes the following steps: [10] Backwash: Water is directed through the resin in the direction opposite to that of normal flow, and the output is sent to a drain for disposal. This ten-minute process flushes out solids, and expands the resin bed.

Carbonate Hardness - an overview | ScienceDirect Topics

Temporary hardness Temporary or carbonate hardness and alkalinity frequently, but not always, mean the same thing (see below). Bicarbonate or hydrogen carbonate is a more scientific term since alkalinity is actually the concentration of the bicarbonate (HCO ¨C3) ion in the water.

Water | Free Full-Text | Review of Techniques to Reduce and Prevent Carbonate Scale. Prospecting in Water Treatment by Magnetism and Electromagnetism

Carbonate scale is one of the main problems in hot water systems, and therefore, interest in this subject has grown since 2000s. Water treatments, based on magnetic and electromagnetic (EM) techniques to prevent scale, are being commercialized, but their effectiveness is not clearly demonstrated because it depends on temperature, pressure, dissolved CO2, pH, field intensity, water flow, etc

a new process to further remove dissolved organic matter and disinfection by-product formation potential during drinking water treatment

A new process to further remove dissolved organic matter and disinfection by-product formation potential during drinking water treatment

Biological activated carbon (BAC) will produce soluble microbial products (SMPs), which affect effluent quality. To clarify the mechanism by which BAC affects effluent water quality, the processes of a drinking water plant in Jiangsu Province were investigated. It was found that during the O3-BAC process, although ozonation could remove dissolved organic matter (DOC) to a certain extent, the

Onsite defluoridation system for drinking water treatment using calcium carbonate

This paper investigates calcium carbonate as a cost effective sorbent for an onsite defluoridation drinking water system. Batch and column experiments were performed to characterize F? removal properties. Fluoride sorption was described by a Freundlich isotherm model, and it was found that the equilibrium time was approximately 3 h.

Bacterial Colonization of Pellet Softening Reactors Used during Drinking Water Treatment - PMC - National Center for Biotechnology Information

The data revealed pellet colonization at concentrations in excess of 500 ng of ATP/g of pellet and reactor biomass concentrations as high as 220 mg of ATP/m 3 of reactor, comprising a wide variety of different microorganisms. These organisms removed as much as 60% of AOC from the water during treatment, thus contributing toward the biological
