Inject the conversation into your bean and in the @PostConstructor method start the conversation if the conversation is transient.

And after deleting the record, end your conversation and navigate to your destination page. When beginning a conversation. Here is an example

public class BaseWebBean implements Serializable {

private final static Logger logger = LoggerFactory.getLogger(BaseWebBean.class);
@Inject
protected Conversation conversation;

@PostConstruct
protected void initBean(){
}

public void continueOrInitConversation() {
        if (conversation.isTransient()) {
            conversation.begin();
            logger.trace("conversation with id {} has started by {}.", conversation.getId(), getClass().getName());
        }
    }

public void endConversationIfContinuing() {
        if (!conversation.isTransient()) {
            logger.trace("conversation with id {} has ended by {}.", conversation.getId(), getClass().getName());
            conversation.end();
        }
}

}

@ConversationScoped
@Named
public class yourBean extends BaseWebBean implements Serializable {
    @PostConstruct
    public void initBean() {
        super.initBean();
        continueOrInitConversation();
    }

    public String deleteRow(Row row)
    {
        /*delete your row here*/
        endConversationIfContinuing();
        return "yourDestinationPageAfter removal";
    }

}
