What we supply
Bleaching powder is made by passing chlorine over slaked lime. What you buy is a mixture of calcium hypochlorite with calcium chloride and lime, and what you pay for is its available chlorine — the part that actually disinfects and bleaches.
Velora supplies stable bleaching powder at 33% minimum available chlorine at despatch, in 50 kg drums. "Stable" grades are made to lose chlorine more slowly in storage, which matters in Indian summer heat. For higher-strength or granular calcium hypochlorite, ask — it is a separate product.
Grades & packing
These are the formats we most commonly supply. Other concentrations, packing sizes and pack marking are available — ask at the enquiry stage.

Handling & storage
Worth reading before you order rather than after. If any of this is a problem at your site, tell us — it usually changes what we would quote.
Price
The price follows chlorine and lime costs and the chlor-alkali balance, and demand rises sharply around the monsoon when municipal and public-health buying peaks. Drum size, freight and quantity set the rest. We quote per kg in writing, and we state the available-chlorine basis so quotes can be compared fairly.
Questions
Yes — it is widely used for disinfecting water storage tanks and wells. The dose depends on the water volume and its chlorine demand, so follow the procedure set by your local health authority or water engineer, and let the treated water stand for the prescribed time before use.
Available chlorine decays over time, faster when drums are left open, damp or hot. Buying in quantities you will use within the season and storing the drums properly is the only fix.
Both disinfect with hypochlorite, but bleaching powder is a calcium-based solid and sodium hypochlorite is a liquid. Liquid suits dosing pumps; powder keeps its strength better than liquid hypochlorite, so it suits sites that dose by hand or store for weeks rather than days.
Bleaching powder is quoted per kg, landed, at a stated available-chlorine level. It follows chlorine and lime costs and rises with monsoon demand. Compare quotes on available chlorine, not only price per kg.
