Simple explanations
Technical topics are broken into practical steps, formulas and examples without unnecessary complexity.
About Ramven
Practical engineering, explained simply.
Hi, I’m Venkatesha Perumal. I work in technical sales in the chemical and water-treatment industry, supporting industrial customers with practical solutions for water, process chemicals and plant utilities.
Ramven is my independent knowledge space for sharing useful engineering articles, calculators and books. The aim is simple: turn technical subjects into clear information that engineers, operators and young professionals can actually use.
Why Ramven
Knowledge from the practical side of industry
Useful tools
Calculators are designed around day-to-day engineering questions such as dosing, blowdown, RO performance and flow conversion.
Independent learning
Ramven is separate from my office work. It is a place to share general engineering knowledge without publishing confidential client or company information.

A note on technical content
Use Ramven as a practical reference, not a substitute for site-specific engineering.
Water chemistry, equipment design and chemical dosing depend on operating conditions, metallurgy, product specifications and local requirements. Always verify calculations against your plant data, OEM guidance, SDS/TDS information and approved site procedures.
