Important physical and chemical parameters provide information about water purity and contamination. Temperature influences chemical reactions, biological activity, and dissolved oxygen levels. Total Dissolved Solids (TDS) indicate the concentration of dissolved salts and minerals, while Total Solids (TS) represent the combined amount of dissolved and suspended matter. Total Suspended Solids (TSS) measure particles such as silt, clay, and organic matter present in water. Hardness, mainly caused by calcium and magnesium ions, affects soap consumption and scaling. Alkalinity indicates the buffering capacity of water against pH changes. Chloride content helps identify salinity and contamination sources. Residual chlorine confirms effective disinfection. Acidity and pH determine the acidic or alkaline nature of water and influence treatment processes. Conductivity reflects the concentration of dissolved ions, while carbonate and bicarbonate ions contribute to alkalinity and water stability.", "item_img_path" : "https://covers4.booksamillion.com/covers/bam/6/63/019/297/6630192974_b.jpg", "price_data" : { "retail_price" : "56.00", "online_price" : "56.00", "our_price" : "56.00", "club_price" : "56.00", "savings_pct" : "0", "savings_amt" : "0.00", "club_savings_pct" : "0", "club_savings_amt" : "0.00", "discount_pct" : "10", "store_price" : "" } }
