What are the typical dosage concentrations of HPMA in different applications?

Posted on By admin No Comments on What are the typical dosage concentrations of HPMA in different applications?

The typical dosage of HPMA (Hydrolyzed Polymaleic Anhydride) varies significantly depending on the application, water quality, and system operating conditions. HPMA is a low-toxicity, high-efficiency scale inhibitor, particularly effective against calcium phosphate and carbonate scales. It also acts as a dispersant for particulate matter like clay and iron oxide. Here is a breakdown of its typical…

Is PESA an environmentally friendly product?

Posted on By admin No Comments on Is PESA an environmentally friendly product?

PESA (Polyepoxysuccinic Acid) is widely recognized as an environmentally friendly product and is often classified as a “green” chemical. Here’s a detailed breakdown of why it holds this reputation: Key Environmental Advantages of PESA: Biodegradability: Unlike many traditional scale inhibitors (e.g., phosphonates like HEDP), which are persistent in the environment, PESA has been shown to be readily biodegradable. It…

What is the optimal concentration range for PBTC?

Posted on By admin No Comments on What is the optimal concentration range for PBTC?

Determining the optimal concentration range for PBTC (2-Phosphonobutane-1,2,4-Tricarboxylic Acid) is crucial for its effectiveness and cost-efficiency. There is no single universal dose, as the optimal range depends heavily on the specific application and water chemistry. However, we can define highly effective and practical concentration ranges for its primary uses. Here’s a detailed breakdown: Executive Summary: Quick…

PASP working principle in oil fields

Posted on By admin No Comments on PASP working principle in oil fields

The working principle of Polyaspartic Acid (PASP) in oil fields is fundamentally different from its use in agriculture, though it leverages the same core molecular properties. In oil fields, PASP is primarily valued as a green and highly effective scale inhibitor. Here’s a detailed breakdown of its working principle and applications: Core Working Principle: Scale Inhibition…
