The disclosure, in one aspect, relates to hybrid ion-exchange and algae photosynthesis systems and processes for algae cultivation and treatment of high NHconcentration wastewater. The disclosed systems and methods can be further optimized using a disclosed mathematical model that can predict the hybrid ion-exchange and algae photosynthesis process including temporal evolution of the NHconcentration. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present invention.

Systems and processes for wastewater treatment

An ammonia adsorption product is described which may be used for fresh caught fish and bait. The product may comprise functionalized tectosilicate compound and a buffer. High concentrations of ammonia produced by fish waste can be lethal, even though oxygen availability is rich enough to keep fish breathing. The product is a user-friendly, sustainable, affordable product which is able to extend the life of the fish by safely removing ammonia by an ion-exchange mechanism. This product can convert toxic ammonia into ammonium and uptake ammonium by releasing sodium ions in the water.

System for removing ammonia from a freshwater environment

The invention relates to a system and method to reduce perchlorate in wastewater utilizing perchlorate-reducing bacteria, sulfur as an electron donor and mollusk shells as alkalinity agent. Embodiments of the invention include a perchlorate-reduction system comprising a bioreactor unit having perchlorate-reducing media comprising elemental sulfur, oyster shells and a microbial community, and can further include an optional pretreatment unit, wastewater-catchment and/or post-treatment components. Embodiments of the method include multiple steps utilizing the system and additional process steps that achieve enhanced perchlorate reduction.
