How Dipotassium Hydrogenphosphate (DKP) Is Used in Water Treatment: Practical Application Guide

Dipotassium Hydrogenphosphate (DKP) (磷酸氢二钾) is one of the most widely specified water plant auxiliary chemicals used across municipal and industrial facilities. As a DKP buffer, it delivers reliable performance in the scenarios our customers ask about most: Buffers, additives, fertilizers, water treatment agents, detergent auxiliaries, softeners.

What Dipotassium Hydrogenphosphate (DKP) Is and How It Works

Dipotassium Hydrogenphosphate (DKP) is supplied as White powder or crystal. Its molecular formula is K2HPO4 (CAS 7758-11-4). Because of this physical form it dissolves and disperses predictably, which makes dosing and process control straightforward for plant operators.

Primary Applications

Its key application areas include: Buffers, additives, fertilizers, water treatment agents, detergent auxiliaries, softeners. In practice this means DKP buffer is selected for both routine maintenance and shock-treatment programs, depending on the water matrix and treatment goal.

• Process reliability: stable active content and consistent granule/tablet size improve dosing accuracy.

• Compatibility: works within existing dosing and storage setups common to water plant auxiliary chemicals programs.

• Logistics: available in 25kg/bag, simplifying import and warehouse planning.

Why Buyers Choose This Grade

When specifying Dipotassium Hydrogenphosphate (DKP), buyers typically compare active content, packaging and the applicable standard (GB 25561-2010). Selecting the right grade reduces consumption and protects downstream equipment.

Operators who also run complementary programs often pair this product with Disodium Hydrogen Phosphate (DSP) to cover the full treatment chain from clarification to disinfection.
