This tech talk will introduce the process of identifying and joining polyvinyl chloride (PVC) pipe using primer and cement. Plastic pipe made of PVC is commonly used in aquaculture applications to contain and direct the flow of untreated or treated water and pressurized gasses in and around the production system.
In order to maintain optimal water quality parameters, specifically with dissolved nitrogen waste products, an aquatic system must have a functioning biofilter. A biofilter is a specific unit within the system’s process flow where water is directed and treated using beneficial microorganisms intentionally grown on specific media. It can be a challenge to jump-start and cycle a biofilter in a new aquatic system.
What do we do with the ozone once it's been made? The possibilities are endless. The effectiveness of ozone correlates directly with the amount of ozone over a period of contact time, usually expressed as mg/L x CT. An example is 1mg/L for 2 minutes contact time. In this column we will discuss some of the most common options for ozone contact and injection.
Dissolved oxygen levels in water are dependent on several environmental factors, including temperature, altitude (barometric pressure), salinity. There are a variety of meter types available for use in the field these days, from the simple dissolved oxygen and temperature to the all-inclusive multi-parameter units.
No matter how well a system is designed or installed, there will always be times when water quality will have challenges. It is critical to be able to test the water to understand the actual challenge.
As things continue to heat up and Aquaculture Industry it is becoming more and more important to understand the key pieces to success. One piece to be in successful is to avoid waste. As we all know, the lower the production cost, the more possible profit there is to be had and a quicker return on investment.
When deciding to either enter the RAS world or modify existing systems, it is important to consider several things. Here’s the caveat: to be clear, this article is not exhaustive nor am I willing to make the statement that it includes everything. Now that we have dispensed with that, these are the items that consistently crop up during discussions with colleagues and customers.
En reacción a la noticia de la salida de Pentair de la industria, los ejecutivos de Aquatic Equipment and Design (AED) aseguraron a la industria acuícola que todavía tiene "un socio en suministros y diseño acuícola".
"Huy y yo estamos orgullosos de haber podido aprender de Bob y continuar con su misión y valores hoy", dijo Riedel-Stone en un comunicado.
Este es un tema del que se habla a menudo y que tiene seguidores bastante polarizados. En cuanto a los componentes de filtración del sistema que pueden esterilizar el agua, los métodos más comunes en nuestra industria son los rayos UV y el ozono. Ya hemos cubierto los rayos UV y sus complejidades, así que esta vez cubriremos el ozono.
La columna de este número se centra en las bombas centrífugas. Son los motores de agua más utilizados en nuestra industria y, en la mayoría de los casos, los menos entendidos. En teoría, se supone que una bomba de 2 hp consume 2 hp para funcionar correctamente, independientemente de quién la fabrique. Sin embargo, no todas las bombas son iguales. Muchos fabricantes de bombas “juegan” con el número de HP al no agregar la eficiencia del motor para obtener HP de cable a agua.
Uno de los componentes más importantes de un sistema y, en muchos casos, el menos comprendido, es la biofiltración. Si bien los cálculos para los biofiltros se publican en varios libros de texto y existen una multitud de artículos revisados profesionalmente sobre su tamaño, todavía hay mucha lógica difusa que se usa en la industria. El desafío es comprender los peligros de la biofiltración de tamaño inadecuado.
